Abstract: 1,194,661. Coiling wire. SCHLOEMANN A.G. 18 Dec., 1968 [4 Jan., 1968], No. 60181/68. Heading B3E. A laying reel for laying rod or wire in the form of turns, the reel having a shaped laying member 3 whose outlet end portion is curved to form the rod or wire into turns, a fixed annular guide 4 surrounding the outlet end portion of the laying member 3, the internal diameter of the guide 4 being equal to the maximum external diameter of the turns of rod or wire, and a roller 6 following the outlet end of the laying member 3 for rolling on the rod or wire and being movable towards the guide 4 in a substantially radial direction. In operation the wire or rod is fed vertically through the housing 1 and rotary laying pipe 3 to the roller 6. The roller 6 is pivoted to the laying head 2 by means of a bolt 8 so as to be movable radially towards the guide sleeve 4. In order to reduce the radial force applied to the roller 6 to a value which is sufficient to hold the rod or wire without deforming it against a ring 5, the roller 6 is connected to a counterweight 11 through a linkage 9 which is able to move radially relative to the axis of the rod, the mass of the counterweight 11 being such that the frictional resistance produced by the force applied by the roller 6 on the ring 5 is greater than the frictional resistance to the passage of the rod or wire through the laying member 3. When reeling small gauge wire the roller 6 is provided with a collar 19. Finally the rod or wire is laid on a conveyer 13 in turns of equal size. In another embodiment the wire or rod is fed in a horizontal direction and the turns formed move horizontally until their lower parts hit against a butting end 16 which tips the turns on to the conveyer belt 13.

A signal produced, e.g., by the ignition device of the engine, closes an electronic switch 10 for a short period during each engine cycle to cause a capacitor 6 to be charged rapidly from the D.C. supply lines P, N. The voltage across the capacitor switches on a transistor or other electronic switch 3, to permit an ultrasonic oscillator 26 to energize the Piezoelectric transducer 1 of a fuel injection nozzle whereby fuel is injected into the engine. After the switch 10 opens again, the voltage across the capacitor 6 decays at a rate determined by a resistor 7, the resistance of which is variable in response to input signals 12, 13, 14, 15. After a time interval determined by this variable resistance, the switch 3 opens again and fuel injection ceases. The signal 15 may be ambient air-pressure.
